Sunday hats are hats that you wear on Sunday mostly to mass.
In my opinion I believe that women still wear hats at church. I think that it really depends on culture, religion and also region. Thanks

The best thing to wear to a church is something formal and appropriate
Hats on , hats off. If you are Jewish, men should be wearing a yarmulke in Synagogue[ or all the time if thy are Orthodox ], if you are Catholic , it's hats off in church for men. Catholic women used to have to wear some sort of headcovering in church, but not any more.I actually had a nun pin a kleenex on my head with a bobby pin one day. Things change . Hats off inside are generally considered courteous. Of course , yarmulkes are always acepptable anywhere for Jewish men.
At church/ a funeral
Its very polite. Removing your hat in church was a Catholic idea and has nothing to do with politeness. The church was seen as being more sacred than other buildings. Protestants rejected this as superstitious and during the Reformation many refused to remove their hats as a sign of protest (see www.historum.com for more info)
